It looks like you have a numeric property of a Vision component bound to a tag with a string value ("Connected"). Vision has no concept of “transforms”, so you’ll probably want to switch to e.g. an expression binding, using the case function:
https://docs.inductiveautomation.com/display/DOC81/case

case(
    {path/to/tag},
    "Connected", 1, // if value is "Connected", return 1
    "Faulted", 2, // if value is "Faulted", return 2
    0 // if no matched value, return 0
)

Great,thanks but after // the conditions are part of the code or just comments?
